Webpack 2 Tree Shaking - Can't get Karma to work

[rafiwardak2003]

I got tree shaking to work with Angular 2.1/Webpack 2 beta. All seems to be good, except my test runner doesn't work anymore. As soon as I switched TypeScript module from commonjs to es6 (target has remained the same, es5) to get tree shaking working, Karma now blows up. I get a bunch of unexpected token (referring to the ES6 import, and a bunch of other errors, failed to parse file... something.ts. Has anyone had luck getting TypeScript/Tree Shaking working with Angular 2 yet?
